Model/Engineer Michelle Warner tells you how to really light up the room

2. Conductive Thread. Either a lot or a little depending on how many lights you want

3. Lithium polymer rechargable battery. I used this one from adafruit.com, it lasted me through a full 6 hour party and it is still quite small.

4. Lithium polymer recharging USB plug. What's better than having a dress that can plug into your computer?! Here's one I recommend.

5. LEDs in whatever color you want! I used about 30 LEDs but you can add more or less depending on what you want. I bought standard through hole LEDs and twisted the ends to save money but there are also sites that provide you with LEDs ready to be sewn on!

6. Clear nail polish. To secure knots in the thread

Putting it all together is simple!

Figure out where you want the LEDs to go and then figure out how to make a circuit that puts the LEDs where you want them. Take a look at this wikipedia page to learn a little bit about LED circuits: http://en.wikipedia.org/wiki/LED_circuit.

Note: conductive thread is not like wire and has a fairly high inherent resistance (about 10 ohms per foot depending on the type of thread) so I did not end up needing a current limiting resistor in my dress.
